摘要 讨论了集值不完备系统上的两种基本关系:相容关系和拟序关系,论证得到了基于辨识矩阵的集值不完备系统知识约简的方法.在此基础上,讨论了知识约简的算法,并通过实例得到了证实. In this paper two kinds of relations on set-valued incomplete information system are discussed: tolerance relation and preorder relation. The methods of knowledge reduction based on discernibility matrices are obtained. An algorithm of knowledge reduction is described.
